Parking Object Detection Feedback for Adaptive Driver Alerts

Solution Overview

Problem

Conventional vehicle parking systems fail to effectively notify users of undetected objects around a parking space, which can increase the risk of collisions during automatic parking.

Innovation Solution

An information processing apparatus that stores detection object information from past parking sessions and acquires new information during subsequent parking sessions, determining the presence of undetected objects and adjusting the notification aspect, such as alarm volume or type, accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional notification systems are used to alert users of objects around parking spaces, then users are notified of detected objects, but undetected objects remain unnoticed and collision risk persists

Engineering Contradiction:

Improvenotification reliabilityVSAvoidundetected object information

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The system performs preliminary detection during the first parking session to establish a baseline of objects present in the parking space. This preliminary information is stored and later compared with subsequent detections to identify objects that appeared or disappeared, enabling the system to notify users of previously undetected objects before collisions can occur.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements a feedback mechanism by comparing detection results across multiple parking sessions. Detection object information from the first parking is stored and used as reference feedback for subsequent parkings, allowing the system to identify changes and improve notification accuracy based on accumulated information about the parking environment.

Inventive Principle:

Principle #23Feedback

2Reliability

If notification intensity is increased to ensure users notice all objects, then safety improves, but user inconvenience increases due to false or excessive alerts

Engineering Contradiction:

ImprovesafetyVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The notification system applies local quality by differentiating notification intensity based on the specific characteristics of detected objects and their detection history. Objects detected for the first time or showing changes between sessions trigger different notification levels compared to consistently present objects, allowing targeted alerts that maintain safety while reducing unnecessary user inconvenience.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The system dynamically adjusts notification aspects based on the detection results and comparison between parking sessions. When undetected objects are identified through information comparison, the notification aspect is changed to increase attention-calling level. This dynamic adaptation ensures appropriate safety notifications while avoiding excessive alerts for stable, non-problematic objects.

Inventive Principle:

Principle #15Dynamics

3Device complexity

If simple detection systems are used to reduce complexity, then device complexity decreases, but the ability to identify undetected objects and adjust notifications accordingly is lost

AI summary

An information processing apparatus includes: a storage that stores first detection object information; and a processor that acquires second detection object information, in which the processor determines whether an undetected object that has not been detected in the first parking is present, based on the first detection object information and the second detection object information, and changes an aspect of the notification when the undetected object is present.
